奉节长江大桥南桥头高边坡治理

重庆市奉节长江大桥地处齐曜山山脉构造带,断裂褶皱发育,地形陡峻,地质条件复杂,不良地质作用发育,南桥头交叉道口人工边坡高达140 m.经过多方案比较论证,采用了多种措施对边坡进行综合处治,变形监测结果表明治理后边坡处于稳定状态.

Study on High Slope Treatment at the Junctions of South Shoulder of Fengjie Changjiang Bridge

Chongqing Fengjie Changjiang Bridge is located at Qiyao Mountain geological formation zone.The topography is full of steep slope and narrow river valley at the site.The complex geological settings own many faults and folds in the geological formation zone.Geological hazard occurs as well.An artificial slope with height of 140 m was excavated at the junctions of the south shoulder of the bridge.The artificial slope was treated with many methods by comparing design schemes.The results from deformation monitoring show that slope is stable after the treatment.
